While I can't speak for every narcissist, it is possible for some individuals with narcissistic traits to engage in indirect hoovering methods even after blocking someone. "Hoovering" is a term used to describe the attempts of a narcissist to re-engage with or "suck back in" a person they previously discarded or blocked, often for their own self-validation or to reassert control.
Changing profile pictures on WhatsApp or other social media platforms can be a subtle way for a narcissist to provoke a reaction or trigger emotions in the person they blocked, even if the blocked person cannot directly see the changes. They might be aware that the blocked person's family or mutual friends can see the updates and may pass on the information.
It's important to remember that not all profile picture changes or social media activities are attempts at hoovering. People can change their profile pictures for various reasons, and it may not always be connected to their interactions with others. However, when dealing with a person who has displayed narcissistic behaviors, it's essential to be cautious and mindful of potential manipulative tactics.
If you find yourself in a situation where you suspect hoovering or manipulation, it's best to focus on your own well-being and emotional healing. Maintain healthy boundaries, limit exposure to triggers if possible, and seek support from friends, family, or a mental health professional to navigate through any challenges caused by such interactions.
